when have you seen him with a grey neck without his helmet? the only instance I know of where you can see his neck while he's suited up without his helmet is in the opening of mega man 4, and his neck is clearly flesh colored there.

His neck is also flesh colored in the Rockman 3 commercial while suited with the helmet, and its pretty hard to argue that it's suppose to be grey. His neck is also flesh colored even after he puts on his helmet in the 4 opening, which is made clear in other media that is not suppose to be the case. Also the credibility of the NES style sprite scenes aren't the most reliable source in this case, blue hair color isn't exactly this figure's strong point.

I guess you're right though, there really isn't any evidence otherwise. I was basing my judgement on ground work set by MML and MMBN subconsciously I guess.

Wow, that really does look great. Will probably be gettin' one for sure. Helmet-less alt though? Now collectors and otherwise must buy two? I think it would be much more convenient to have the head pieces be swappable if that's the only difference between them.

Since this is a soft vinyl figure: the "without helmet" configuration may be achieved by just switching-out the heads; we should just have to buy one figure & get two heads. The rough translation hints at that; the caption beneath that final photo says: "...by replacing the head," so it's possible this will be a single figure with alternate heads.
